You are absolutely right and I am addressing the leak. It is going in to our local French marine workshop this coming Saturday.
I am monitoring this daily and in the mean time flushing out the bilge with soapy water to avoid a build up of petrol and fumes. I take this very seriously and pretty concerned.
